Abstract

A steel cord (10) for reinforcing elastomeric articles.
The steel cord (10) has a plurality of strands (14). Each strand (14) has a core (20) and a sheath (22). The sheath (22) includes a plurality of steel filaments that are helically wrapped about the core (20). A first strand (16) extends longitudinally through the center of the steel cord (10). The remaining strands (18) are helically wrapped about the first strand (16). The core (20) of the first strand (16) includes a plurality of filaments twisted together. In a preferred embodiment, the core (20) of the first strand (16) includes three filaments twisted together.
